In a prospective study following a validated training module, we found that a selected group of endoscopists identified rectosigmoid neoplastic lesions with pooled NPVs greater than 90% and accurately selected surveillance intervals for more than 90% of patients over the course of 1 year. Providing regular interim feedback on the accuracy of neoplastic lesion prediction and surveillance interval selection did not lead to differences in those endpoints. Monitoring is suggested, as individual performance varied. ClinicalTrials.gov no: NCT02516748; Netherland Trial Register: NTR4635.

Our findings indicate that aging is associated with nutrient-specific changes in appetite, hormonal, and gastric myoelectrical (EGG) responses to i.d. nutrients. An enhanced satiating effect of small intestinal carbohydrates may potentially contribute to the anorexia of aging.
